Abstract

In Algeria, the Globally Endangered White-headed Duck Oxyura leucocephala is resident throughout the year in the coastal wetlands of north-east Algeria and the Hauts Plateaux, where it occupies habitats that range from freshwater ponds and brackish marshes to hypersaline lakes. In autumn and winter, at two study sites sleeping (49% and 68%) and resting (9% and 20%) dominated, whereas feeding (7% and 10%) represented a minor proportion of, diurnal activities. There was no marked seasonal change in the activity pattern, as would be expected for a resident bird. The breeding and winter distributions of the species were similar, but seasonal and diel patterns of dispersion among habitats remain poorly known. Human encroachment on wetland habitat, habitat degradation and illegal hunting in protected areas are the major threats to the persistence of the species and probably similar threatened species in Algeria.
